Each logic array block (LAB) consists of eight adaptive logic modules (ALMs), carry
chains, shared arithmetic chains, LAB control signals, local interconnects, and register
chain connection lines. The local interconnect transfers signals between ALMs in the
same LAB. Register chain connections transfer the output of an ALM register to the
adjacent ALM register in a LAB. The Quartus II Compiler places associated logic in a
LAB or adjacent LABs, allowing the use of local, shared arithmetic chain, and register
chain connections for performance and area efficiency.
